 |
|
I am trying to understand what the output of
is telling me. I have two Dell PowerEdge servers with SATA drives in software RAID-1.
On Server A, cat /proc/mdstat shows this
| Code: | | md2 : active raid1 ide/host0/bus1/target0/lun0/part2[1] ide/host0/bus1/target0/lun0/part2[0] |
On Server B, cat /proc/mdstat shows this
| Code: | | md2 : active raid1 sdb2[1] sdb2[0] |
I know that the RAID-1 is healthy. I am trying to understand why on Server A the devices are shown in such detail while Server B the devices are so simple.
Server A runs a 2.4.x kernel. Server B runs a 2.6.x kernel. The hardware on both servers is the same.
Is this just a differece between the 2.4.x and 2.6.x kernels? Or did I miss something somewhere?
I do note that on Server A in /dev I do not have any sd* devices while on Sever B /dev shows sda-sda10, sdb-sdb10, etc. |

It's not unusual for 2.4 kernels to use such explicit paths for device names. devfs and the backported udev suck.
Get used to this kind of thing, or use 2.6.
